Your translation is pretty good. I'll smooth it out a bit for you. This is me, the one from whom you withheld your graces. I am satisfied with this, I don't know if I will return to my family from this dangerous trip. I don't know if this sickness will begin or not! (I can't think of a better word than "begin" but "take off" sounds odd to me.) I don't know who to complain to about you!

Hassan, what is it that you want to do with this translation?
